<h1>PIA01968: Saturn's moon Mimas</h1><div class="PIA01968" lang="en" style="width:140px;text-align:left;margin:auto;background-color:#000;padding:10px;max-height:150px;overflow:auto;">The cratered surface Saturn's moon Mimas is seen in this image taken by Voyager 1 on Nov. 12, 1980 from a range of 425,000 kilometers (264,000 miles). Impact craters made by the infall of cosmic debris are shown; the largest is more than 100 kilometers (62 miles) in diameter and displays a prominent central peak. The smaller craters are abundant and indicate an ancient age for Mima's surface.

<h1>PIA02266: Mimas - large impact structure</h1><div class="PIA02266" lang="en" style="width:363px;text-align:left;margin:auto;background-color:#000;padding:10px;max-height:150px;overflow:auto;">This Voyager 1 picture of Mimas shows a large impact structure at 110 W Long., located on that face of the moon which leads Mimas in its orbit. The feature, about 130 kilometers in diameter (80 miles), is more than one-quarter the diameter of the entire moon. This is a particularly interesting feature in view of its large diameter compared with the size of the satellite, and may have the largest crater diameter/satellite diameter ratio in the solar system. The crater has a raised rim and central peak, typical of large impact structures on terrestrial planets. Additional smaller craters, 15-45 kilometers in diameter, can be seen scattered across the surface, particularly along the terminator. This photo was taken on November 12 at 5:05 a.m. PST, from a range of approximately 660,000 kilometers (400,000 miles). Mimas is one of the smaller Saturnian satellites with a low density implying its chief component is ice.

The photograph, taken at a range of 208,000 kilometers (129,000 miles), shows features as small as about five kilometers (three miles). Topography is best seen along the terminator where it is enhanced by the low sun angle. The apparent crater density decrease toward the left of the picture is not real and results from a change in sun angle. A long, narrow trough about five kilometers (three miles) across is seen to cross from lower limb to the center of the image where it terminates. A second trough originates near the center and extends to the upper limb, where it appears to branch into a series of smaller troughs.

Delicate shadows cast by the rings arc gracefully across the planet, fading into darkness on Saturn's night side.</p><p>The part of the atmosphere seen here appears darker and more bluish than the warm brown and gold hues seen in Cassini images of the southern hemisphere, due to preferential scattering of blue wavelengths by the cloud-free upper atmosphere.</p><p>The bright blue swath near Mimas (398 kilometers, or 247 miles across) is created by sunlight passing through the Cassini division (4,800 kilometers, or 2,980 miles wide). The rightmost part of this distinctive feature is slightly overexposed and therefore bright white in this image. Shadows of several thin ringlets within the division can be seen here as well. The dark band that stretches across the center of the image is the shadow of Saturn's B ring, the densest of the main rings.

Mimas has been so heavily cratered that new impacts can only overprint or even completely obliterate other older craters. Mimas is 397 kilometers or (247 miles) across.</p><p>The moon displays an unexpected array of crater shapes. The highest crater walls tower 6 kilometers (4 miles) above the floors and show signs of material sliding down slope. Indeed, many of the large craters -- more than 15 kilometers (10 miles) in diameter -- appear to be filled in with rough-surfaced material, likely the result of landslides triggered by subsequent impacts elsewhere on Mimas' surface. Some of these deposits have craters superimposed on them, demonstrating that the landslides themselves may be quite old.</p><p>Grooves, some of which are over a kilometer deep, cut across the surface for more than 100 kilometers (63 miles).

Next, the famous Cassini division (4,800 kilometers, or 2,980 miles wide) separates the A and B rings. The outer edge of the B ring which forms the inner boundary of the Cassini division is maintained by a gravitational resonance with Mimas. Near the outer edge of the A ring are the Encke Gap (325 kilometers, or 202 miles wide) and the barely visible Keeler Gap (35 kilometers, or 22 miles wide). The faint, thread-like F ring is discernible just beyond the main rings.</p><p>The image was obtained with the Cassini spacecraft narrow angle camera on August 27, 2004, at a distance of 9.1 million kilometers (5.6 million miles) from Saturn.

Ultraviolet images of Saturn's moons often reveal the walls of their myriad craters in greater contrast than do images taken in visible light. This view, which shows the large impact crater Herschel, is no exception. Mimas is 397 kilometers (247 miles) across.</p><p>The image was taken with the Cassini spacecraft narrow-angle camera using a filter sensitive to wavelengths of ultraviolet light centered at 338 nanometers. The image was acquired on Feb. 18, 2005, at a distance of approximately 938,000 kilometers (583,000 miles) from Mimas and at a Sun-Mimas-spacecraft, or phase, angle of 99 degrees. The image scale is 6 kilometers (4 miles) per pixel.</p><p>The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency.

Part of Saturn's immense shadow makes a dark, fingerlike projection into the rings, as seen here. Mimas is 397 kilometers (247 miles) across.</p><p>North on Mimas is up and to the left. This view shows principally the Saturn-facing hemisphere on Mimas.</p><p>The image was taken in polarized green light with the Cassini spacecraft narrow-angle camera on March 7, 2005, at a distance of approximately 1.5 million kilometers (900,000 miles) from Mimas and at a Sun-Mimas-spacecraft, or phase, angle of 30 degrees.
